8 Signs Your Car Needs a Professional Mechanic


Rev Auto & Truck Repair in Denver, CO Is Here To Help

Is my car broken?

It can be tricky to tell whether your car needs a break or immediate attention from a mechanic. If you notice any of the signs we've listed below, we strongly recommend having your vehicle checked by a professional mechanic sooner rather than later. Taking action early can help you avoid more severe damage and expensive repairs later on.


1. Car Experiences Stalling

Is your car stalling or struggling to accelerate, no matter how hard you press the gas pedal? This isn't just inconvenient-it could indicate serious issues like a failing fuel pump or ignition problems, which are hazardous to face while driving. Don't wait and hope the problem resolves itself. Bring your vehicle in for a check up from our team of experts.


2. Trouble Steering

If your steering wheel becomes difficult to maneuver or your turns aren't as smooth as they used to be, it could signal an issue with essential steering components. Possible reasons could be low power steering fluid or other mechanical failures. It's crucial to address any problems that impact your ability to steer the car safely-seek immediate professional assistance at an auto repair shop.


3. Fluid Leaks

If your vehicle is leaving behind puddles of liquid, it's a sign you should investigate further. While water from air conditioning condensation is usually harmless, other fluids like oil, transmission fluid (red or brown), coolant (blue, yellow, green), power steering fluid, or brake fluid (thick but clear) indicate a potential leak in one of your car's critical systems. Addressing these leaks promptly can prevent further damage and ensure optimal performance. It's advisable to have these issues inspected and remedied by a specialist.


4. Worn Out Brakes

Brakes naturally wear down over time and if you notice them losing effectiveness or making unusual noises, it's a sign they may need attention. Screeching or squealing often indicates that the brake pads are worn and require replacement. Additionally, if your brakes shake or vibrate, this could point to a range of issues, from further wear on the pads to problems with the brake fluid or alignment.


5. Alignment Issues

If you've noticed your car's ride has become notably less smooth in the past few months, it might be time for a trip to the auto shop. A shaky or vibrating ride, especially at higher speeds, often stems from wheel or alignment issues.

Even after a proper wheel alignment, wheels can gradually shift, influenced by normal wear and tear or sudden incidents like accidents or unexpected bumps. Realignment is a straightforward procedure that can swiftly address the issue.


6. Uncommon Engine Noise

Engines are meant to run smoothly, so if yours starts to sound louder with age, that's normal. But if you hear sudden, unusual noises like grinding, popping, or growling-or if starting your engine becomes a struggle-it's a good idea to visit your local auto shop. Catching these warning signs early can help ensure your car stays in top shape!


7. Diagnostic Lights

Modern vehicles are equipped with engine diagnostic or check engine lights that sometimes activate not because of an immediate issue, but as reminders for routine checkups after a certain mileage has been reached.

In some instances, a glitch in the car's computer system might even trigger these lights without any actual problem. However, when these lights come on alongside other symptoms such as poor performance or strange noises, it's wise to get your car checked by a professional to ensure everything is running smoothly.


8. Unpleasant Exhaust

If you notice your exhaust emitting black smoke or strange odors, it might be time to check in with a mechanic. This could indicate something like a clogged filter or another issue with your car's systems, possibly even the catalytic converter. It's always a good idea to get these things looked at to keep your car running smoothly.

The owners and operators of this place deserve the world. I failed my emissions test yesterday and was originally quoted at $200 for inspection. The inspection went much more quickly than expected and they were able to fix the issue with very little effort. They ended up not charging me a penny because it was such an easy fix. I am immensely grateful to Liz and Mike for saving me an anxiety inducing expense. Unmatched customer service, truly! quotes-image

I had my 2022 F-150 inspected at Rev Auto after purchasing it, and this was one of the best experiences I’ve ever had with an auto repair shop. The service advisor Liz was friendly and knowledgeable, and she did a great job of explaining everything in a way that helped me make informed decisions. Their inspection was incredibly thorough. They documented everything with photos, took a sample of my transmission fluid before recommending service, and even gave me an honest assessment of the truck’s undercarriage and light surface rust. At no point did I feel pressured into unnecessary repairs. Instead, they took the time to answer my questions, explain their recommendations, and help me prioritize maintenance. What impressed me most was that they actually talked me out of a more expensive transmission fluid because it wasn’t necessary for how I use my truck. That level of honesty is rare. It’s hard to find a shop that combines technical expertise with integrity and excellent customer service, but I think I found one. Rev Auto has earned my trust, and they’ve definitely become my go-to shop for my truck. Highly recommend.quotes-image
